For something as simple as this, PIL is not really needed - you can do it with numpy fliplr.
import matplotlib.pyplot as plt
import numpy as np
im = np.flipud(plt.imread('so.jpg'))
plt.subplot(2, 1, 1)
plt.imshow(im)
plt.subplot(2, 1, 2)
plt.imshow(np.fliplr(im))
plt.show()

You have stated you are using PyGraphics - it states that load_image returns a PIL image object.
PyGraphics doesn't appear to offer the functionality of flipping, so just do it with PIL, specifically transpose
from PyGraphics import picture
flipped = picture.load_image("blah.jpg").transpose(Image.FLIP_LEFT_RIGHT)

You should look at the PIL for such things :)

This may be the simplest way to do what you wan.
Here is a tutorial that will give the code :
